Given that Elementary is a new show (with it's 1st season still showing on Sky Living) and all the others listed are (I believe) onto their 2nd or later series I would guess all you are getting for now is the Elementary Pilot.

These episodes of Modern Family, Mad Dogs and Boardwalk Empire have already been shown on Pick TV (or Sky 3 as it used to be) before but the rest have not as far as I know (I don't think I would have noticed some of them like Richard E Grant's Hotel Secrets.)

But Terra Nova and Warehouse 13 appear to be the full series - on Sunday nights and repeated on Saturdays. (Strike Back is also the full series but has been shown on Pick TV twice already.)

More like a warning, you mean?
Essentially it says: if you buy the Sky package, this is the sort of stuff you'll get. So don't say we didn't tell you.

(Though what they aren't telling you is that the weekly new episode of practically everything they broadcast is shown 3 or 4 times in a week. And then again after the series finishes, and again a few months later then again until the "tape wears out" or their contracted number of screenings is met.)

I'll give Game of Thrones a go because I've heard so much about it but none of the others look very interesting.
Considering how good freeview is and the relatively low cost of many boxsets (which you get to keep, advert free), I don't plan to ever give Sky a penny of my money. If they want to continue trying to tempt me with events like this then I'll quite happily take advantage but they should know that I'm immune to their tactics

I've already got boxed sets of Stella and Game of Thrones but I'll give Elementary, Touch, Blue Bloods, Spy, and A Young Dr's Notebook a go to see what boxed sets to put on my Christmas list!

I watched those episodes of Mad Dogs and Boardwalk Empire when they showed them as part of the Free Weekend Pass and wasn't bothered about not getting to see any more of them. The same with Pacific when they showed the beginning of that - it worked fine as a movie on its own but I wasn't interested enough in any of the characters to care whether I saw what happened next.

Apparently Treasure Island is being shown in full, but it doesn't look like my kind of thing.
